HENRY D. STREATOR, 0F GALESBURG, MICHIGAN.

MOLD.

To all whom it may concern:

Be it known that I, HENRY D. STREATOR, a citizen of the United States, residing at the village of Galesburg, county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Molds, of which the following is a specification.

7 This invention relates to improvments, in molds for plastic materials such as concrete and the like.

The main objects of this invention are, first, to provide an improved mold which is capable of very rapid manipulation. Sec 0nd, to provide an improved mold which is capable of being adjusted to produce difi'erent size blocks or posts, straight or tapered as desired. Third, to provide an improved mold which is adapted to be adjusted for producing different sizes of blocks or producing tile or conduit. Fourth, to provide an improved mold which is strong and durable and comparatively simple in structure.

Further objects, and objects relating to structural details, will definitely appear from 2 5 the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The structure described constitutes one efiective embodiment of my invention. Other embodiments would be readily devised by those skilled in the art.

The invention is clearly defined and pointed out in the claims.

A structure constituting an effective and preferred embodiment of the features of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which,

Figure 1 is a plan View of a structure embodying the features of my invention, the same being adjusted as a post mold a post being shown therein. Fig. 2 is a side elevation of the structure appearing in Fig. 1.

Fig. 3 is an end elevation thereof. Fig. 4 is a detail plan view of the structure collapsed, the bottom being removed. Fig. 5 is a cross-section taken on a line corresponding to line 5-5 of Figs. 1, 2 and 4, one of the clamping arms being indicated in its open position by dotted lines and one of the side walls being indicated in its collapsed position by dotted lines.

Fig. 8 is a vertical section taken on a line corresponding to line 8-8 of Figs. 3 and 4, the end wall being removed. Fig. 9 is a detail perspective of a modified construction in which the side walls are provided with vertical grooves to receive the adjustable partitions for use in producing blocks of different length. Fig. 10 is a detail perspective of my improved mold adjusted as a tilemold. Fig. 11 is an enlarged detail vertical section taken on a line corresponding to line 1111 of Fig. 10. Fig. 12 is a detail perspective of one of the side walls of the structure shown in Fig. 10, an end wall being shown by dotted lines in engaging position. Fig. 13 is a perspective view showing my improved tile as constructed with the mold illustrated in Figs. 10 and 11.

In the drawings, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the longitudinal frame bars 1 are preferably formed of sections of pipe as they are rigid and are Well adapted to serve as a pivot for the side walls. These bars are preferably provided with the supporting members 2 at each end which are adjustably connected to the end pieces 3, the end pieces being slotted at 4 to receive the bolts 5, see Fig. 7. The members 2 are preferably provided with holes 6 to receive the end of the bars, the bars being clamped therein by the set screws 7. Thus supported the bars can be readily adjusted to and from each other to secure the desired width and also the taper of the posts or blocks. The

bars 1 are also preferably connected by a ends of the cross-piece sections so they can These sections are be readily engaged.

whereby they are adjustably secured. The ends of the cross-pieces are preferably extended outwardly and upwardly to serve as supports for the side walls 12 of the mold when they are collapsed and also as supports for the side wall clamping arms 13 which are pivoted thereon at 14. These clamping arms are arranged to swing inwardly to engage the side walls as is illustrated in Fig. 5. The clamping arms 13 are preferably provided with cam-like engaging members 15.

The side walls are. preferably channel shaped in cross-sections as illustrated for the sake of strength and lightness. lVhere they are designed for post molds the side walls are preferably. provided with the vertical ribs 16 suitably spaced to form wire engaging grooves on the post.

The end pieces and the cross-piece are preferably adapted to serve as supports for thebottom 17. This bottom is preferably in the form of a plank so that it may be removed and form a drying pallet for the post or blocks. Arranged transversely under the bottom and preferably supported by bear ings lS'carried by the bars 1 is a bottom clamping cam 19, the cam being preferably in the form of a shaft and having a projecting end 20 which may be engaged with a foot to clamp thebottom up against the under edges of the side walls and end walls when they are in their erected position.

The side walls are pivotally supported, they being preferably provided with armlike hinge members 21 having curved socketlike ends 22 adapted to engage the bars 1. These hinge members are open on one side so that the side walls can be lifted from the mold as desired'for transporting, or storage, or for changing as occasion may require.

The end walls 23 are pivoted on the end pieces, the end pieces being provided with hook-like hinge members 2st to engage the pintles or pivots 25 on the end walls so that the end walls can be removed readily when the mold is adjusted, it being intended that when the mold is adjusted end walls of the proper length shall besubstituted. The end walls are preferably provided withrests 37 by which they are supported in their collapsed position.

The side walls are provided with end wall supports 26 which are adapted to engage the end walls when theyare erected and the side walls swung to their erected position.

By thus arranging the-parts I secure a mold which can be very quickly manipulated in the manufacture of'posts or blocks. hen

adjusted to the proper size the operations are as follows: The pallet or bottom is laid upon its supporting rest, consisting preferably as stated of the-end and crosspieces; the end walls are swung to their erected position and the side walls then erected and clamped upon the end walls by means of the clamping arms 13. The cam 19 is then ac tuated to clamp the bottom against the lower edges of the walls. The material to be molded is then placed in the mold and tamped or packed as desired; the walls are then collapsed and the molded objects carried away upon the bottom as a pallet. This operation can, as stated, be very quickly carried out. The adjustment of the mold to different objects and different formed objects has been explained.

In the modified construction shown in Fig. 9 the side walls are provided with vertical grooves 27 to receive the partitions as 28; the mold can thus be divided into suitable sections according to the articles that are to be produced.

In the modification shown in Figs. 10 and 11 which is adjusted as a tile mold the end walls 29 are adapted to support the core 30, the core 30 being suitably conformed to form the channel in the tile sections as 31 and 32, the section 32 being the top section and the section 31 the base section, the tile sections thus being horizontally divided. The core 30 is provided with a series of holes to receive the supporting pins 34 which are carried by the springs 35 mounted on the end walls.

Vhen it is desired to manufacture the top section in which the channel is more shallow than in the base section a false bottom or pallet is preferably provided, one or more pallets may be used as desired according to the depth of the tile section it is sought to manufacture. By thus arranging the parts I produce a mold which is adapted for the manufacture of tapered posts or posts of uniform crosssections from end to end; also by providing the side walls with slots or grooves to receive the partitions a block of any suitable length or shape can be produced with the same mold. I also illustrate the adaptation of the same to a tile mold.

I have illustrated and described my improved mold in detail in the form in which I have found to be practical. I am, however, aware that it is capable of considerable variation in structural details without departing from my invention and I desire to be understood as claiming the same specifically as illustrated as well as broadly within the scope of the appended claims.
